Abstract
An anti-vibration device according to the present invention makes it possible to achieve compactness and sufficient durability without increasing the number of parts. To be specific, an anti-vibration memberis made up of an inner cylinder, an outer ring, and a rubber-like elastic body. The outer ringis disposed outside the inner cylinder. The outer ringis attached to a frame-side member. An end plateis provided at an outer end portion of the inner cylinder. The rubber-like elastic bodyis disposed between the inner cylinder, the outer ring, and the end plate. The anti-vibration rubber assemblyis provided on each side of the frame-side member. A guide memberis interposed between the two inner cylindersand is unified therewith. The inner cylinderis attached to an engine-side bracket. The guide memberfaces the outer ringin the radial direction and guides the inner cylinderin the up-and-down direction. Damage of the rubber-like elastic bodydue to displacement in the horizontal direction is prevented while an engineis elastically supported thereby suppressing vibration.
